A camera having highlighting for the subject of the photograph and detection of motion of the subject. The camera detects the scene electronically and digitally stores the scene in memory. A gradient operation is performed on elements in the image to produce an indication of the outline of the subjects witin the depth of field. This outline may then be used to highlight the subjects in the viewfinder using an LCD as a mask. The outline may also be used to determine any movement of the subject in order to prevent blur or used as a trigger in a burst exposure mode.
